XF 1.5 Robots.txt and Sitemaps on Webmaster Tools.


Well-known member
Robots.txt you have to create yourself. You can base it on Xenforo's if you wish https://xenforo.com/robots.txt. Search this site and you'll find several threads about what to include.

You can generate a sitemap and automatically submit it to search engines using the Sitemap options in the ACP. You can then submit that to Google Webmaster Tools.
